comment How to photograph a footprint on metal?
If the print has some sort of depth (positive or negative) you can try using a very low level light (darkfield) to emphasize it.

comment Star photography
@JohannesD true for this image but not always the camera movement is the cause, with a 30 second exposure time, it is obvious that rotational speed of the earth is in effect too.

comment Noticible diff. using Display port versus DVI on Eizo ColorEdge Monitor?
If we talk about CIE1994 graphic arts deltaE value of color difference with using standard D65 white point and sRGB, in theory between DVI(8bits per channel) and DP(10bits per channel), a maximum value of 0.18 deltaE difference/error can be exist. So 0.18 dE is really low to be able to distinguish with human eye.

If you read the question, issue here is not the lacking of the cable but the graphics card.

comment RGB colour correction of CCD camera images
In the beginning poster had doubts on CCD quality and chromatic aberration, finally we have concluded that issue is caused by the sensor or at the reconstruction step of the camera which both IMHO makes this question relevant.

comment RGB colour correction of CCD camera images
This is actually your preference. I have cropped the image as you can see from the bottom part of it. If you need to keep the original image size, you can choose to put black pixels to suit the background.

comment RGB colour correction of CCD camera images
I see that your image is quantized to 32 levels. And hue is shifted vertically not only close to the edges (ch. aberration) but in the whole image (i.imgur.com/Rcna2de.png). My opinion is, something is wrong with the camera's image processor or worse, CCD.

comment RGB colour correction of CCD camera images
Looks like chromatic aberration but I am seeing that it is present in all of the image. How are you getting your images ? Are you using Bayer filter ? Something can be wrong on the reconstruction step from color coded image. Additionally just an idea, if you are going to check only the QR codes, you can consider using grayscale images.

comment Techniques for photographing stained glass?
Rather than solving this issue completely in shooting, you can always fix it in editing. The solution is to have background as dark as possible while shooting. Afterwards you can adjust "blacks" and "whites" values accordingly with your software as it pleases you.

comment Is image stabilization a necessary feature for wide angle lenses?
@MichaelClark It is good to know that in the new lenses they have addressed that problem, it was a trouble before. Thank you for the information.
